BOOK-MARK.

To all whom it may concern:

Be it known that I, JAY W.

cine, county of Racine, and State of W'isconsin, have invented new and useful Im rovements in Book-Marks, of which the fol owing is a specification.

My invention relates to improvements in book marks.

The object of my invention is among other things to provide a convenient, inexpensive and efiicient means of producing and connecting together a plurality of index marks by which a number of different pages of a book may be indicated, the books readily opened at the indicated points while the particular-line or paragraph of such page may also be indicated while such index marks may be readily removed to another book or changed from one place to another in the same book.

My invention is further explained by reference to the accompanying drawings in which, i

Figure 1' represents a vertical section of a book provided with my marking device, the retaining mechanism of which is shown in vertical section, Fig. 2 represents an end view of a book provided with my marking device, part in section. Fig. 3 represents a modified form of one of the marking members removed from the book, and Figs. 4 and 5 represent horizontal sections drawn on lines XX, and YY of Fig. 1.

Like parts are identified by the same reference characters throughout the several views.

1 represents the side covers, 2 the leaves,

3 the back of the cover, and 4 the back of the binding of a book.

My apparatus comprises aplurality of marking members 5 provided at their respective ends with apertures 6, two over lapping adjustable members 7 and 8 which are slidably connected together by the clamping members 9 and 10 in such a mannor that such members 7 and 8 may be extended and contracted to conform to the length of difierent books, 11 and 12 are loops by which the markin members are connected with. the mem ers 7 and 8. The clam ing member 7 is rovided with an inwar y and downward y extending arm- 13 and the clamping member 8' is provided with an upwardly and inwardly extending arm 14,-

and said/arms 13. and 14" are respectively Specification of Letters Patent.

Application filed January 13, 1908.

inserted in the s aces between the back of lie back of the binding 4.

It will be understood. that the clamping members 9 are formed integrally with the upper end of the member 8 and that it partially incloses the opposing member 7, also that the members 10 are formed integrally with the member 7 and partially inclose's the member 8 as indicated in Figs. 4 and 5. That the clamping members 9 engage loosely around the clamping member 7, while the clamping members 10 engage loosely around the clamping member 8 in such a manner as to slidably connect said members .7 and 8 together as stated.

The loops 11 and 12 are formed of a sin is piece of sheet metal bent in a semi-cir'cu a'r form shown and their overlapping ends 15 and 16' are connected with the respective members 7 and 8 at the ends of the book and they serve to hold the several marking mem bers 5 in place. The marking members 5 are respectively provided with angular slits 17 through which the loops 11 and 12 are free to enter the apertures 6 of said marking members as such members are secured in place in a book. The markin members 5 are preferably formed of a cellu oid, a tough qua ity of paper or similar material which is sufiiciently flexible to sidcs of the slits 17 to inserting the loops. For the purpose of shielding the ends of marking members and the retaining loops from contact as the book is handled, 1 preferably provide the slidable members 7 and 8 with the end plates 18, 18, which extend inwardly from the back of the cover to shield such parts. The marking members, 5 serve to indicate the pages of the book, while I have provided the members 20 which are adapted to slide upwardly and downwardly upon the members 5 to indicate the special lines or paragraphs on such pages. The slidable members 20 are preferably provided with index characters arranged numerically in the manner shown which aid the permit the respective user of the book to determine the desired point of opening the same. As a convenient means for fastening the member 20 to the members 5, I have provided the same with two longitudinal slits 21 and 22, when the ends of the members 5 are inserted through the slit 21 above the central tongues 23 and back through the slit 22, when the member 20 will be retained at any. desired point of adjustment by the resilient action of such e sprung apart when scribed class, the combination of two overcooperating parts. While I have shown the 3 marking members 5 within the book, provided at its respective ends with apertures l (5, in the modified form shown in Fig. 3 the i rm'irking member '5 isprovided with but a single aperture 6, and slit 17" while the lower horizontal arm together with the loop retaining aperture is dispensed with.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is,

1. In a book marking device oi the described class, the combination of two overlapping members slidably connected together, means for temporarily connecting; said members with the back of a book, a plul rality of marking members radially connected with said slidable members and adapted to be folded with and between the leaves of a book.

2. In a book marking device of the delapping members slidably connected to-- gether, means for temporarily connecting said members with the back of the book, a loop attached to one of said sliding members, a plurality of longitudinally arranged marking members, and means for slidably connecting said marking members with said loop.

3. In a book marking device of the described class, the combination of two overlapping members slidably connected together, means for temporarily connecting said members with the back of a book, a pluqality of marking members arranged longitudinally of the book, means for temporarily connecting said marking members with said slidablc members, and a transversely arranged marking member slidably supported upon said longitudinal marking member,

4. In a book marking device of the de scribed class, the combination of two overlapping members slidably connected togcther, means for temporarily connecting said members with the back 01 a book, a plurality of marking members arranged longitudinally oi the book, means for temporarily connecting said marking members with said. over-lapping members, a transversely arranged member slidably supported upon each of said 'marking members, the protruding ends of said slidablc marking members being respeztively provided with index characters.

.5. In a book i'narking device of the described class, the combination of two overlapping members slidably connected together, a retaining hook formed integrally with each of said sliding members adapted to engage the back ofthe cover of a book, circular loops connectedwith the ends of said slidable members, transversely arranged end plates connected with the respective ends of said members adapted to shield said loops from contact, a plurality of longitudinall arran ed markin members rovided with apertures for the reception of said loops and. with transversely arranged slits through said members with the back of a book, a loop connected with the outer end of one of said slidable members, protecting end plates formed integrally with the respective endsof such slidable' members, longitudinally arranged marking members provided'at one end with an aperture for the reception of said loop and with a slit through which said loop may enter and be removed from said aperture and a transverselyarranged marking member slidably supported upon said I longitudinal member, all substantially as and for the purpose specified.

In testimony whereof I aliix my signature in the presence of two Witnesses.
